We report real-time detection of single fluorescent molecules in solution with a simple technique that combines confocal microscopy, diffraction-limited laser excitation, and a high-efficiency photon detector. The probe volume, similar to 5.0 x 10(-16) L, is defined latitudinally by optical diffrac...
The electronic dephasing of two oxazine dyes dissolved in ethylene glycol at room temperature is investigated by femtosecond degenerate four wave mixing (DFWM) experiments. Both two-pulse and three-pulse DFWM with simultaneous detection of the signals at two distinct phase-matching directions permits ...

The chain-length dependences of the rotational diffusion constants of nBPVs and ECnTs in solution are determined by time-resolved fluorescence depolarisation measurements and rationalized by a simple model. 展开 关键词: Experimental, Theoretical or Mathematical/ configuration interactions diffusion ...
In the course of a photochemical reaction, reactants are converted into products with the possibility of various transition states and transient intermediates on the reaction pathway. The properties of these transient intermediate species are central to the reaction and determine its rate and selectivity...

In the third step, the Fraunhofer IGB researchers placed the substances in a solution and added them one by one to the specially produced cell lines. In this procedure, known as an assay, the researchers were finally able to identify which substances the cells responded to by means of a col...

results, we decided to explore the plasma-assisted oxidation of small molecules under ambient conditions in solution, and in the presence of the same stable iron compounds as homogeneous catalysts, namely ferrocenecarboxylic acid (A) and hemin (B, Fig.1). In exploratory work we describe in this...
